the MX records have only indirectly to do with what exim thinks...
exim will store what is local, and relay (to the other MX) what it
accepts but is not local. If you want redundancy presumably you want
to have both servers store mail for the same domains (and keep each
other in synch). This is not trivial but can be done. In this case I
would maintain a hierarchy nevertheless, with a preferred MX.
